THE HAGUE: Dutch judges have ordered a man suspected of fathering more than 550 children through sperm donations to stop donating, in the latest fertility scandal to shock the Netherlands.

The man, identified in Dutch media only as “Jonathan M.”, 41, was dragged to court by a foundation protecting the rights of donor children and the mother of one of the children allegedly fathered from his sperm.

Dutch clinical guidelines say a donor should not father more than 25 children in 12 families, but judges said the man had helped produce between 550 and 600 children since he started as a sperm donor in 2007.

The court therefore “prohibits the defendant from donating his semen to new prospective parents after the issuing of this judgement,” judge Thera Hesselink said.

Jonathan M. may also not contact any prospective parents “with the wish that he was willing to donate semen... advertise his services to prospective parents or join any organisation that establishes contact between prospective parents,” Hesselink said in a written judgement.

Hefty fine

Should he continue with his donations, he would face a 100,000 euro ($110,000) fine for every transgression, the judge ordered.

More than 100 children of Jonathan M.’s children were born in Dutch clinics and others privately, but he also donated semen to a Danish clinic named as Cryos in court papers, which then dispatched his seed to private addresses in various countries, the judge added.

“The donor deliberately misinformed prospective parents about the number of children he had already fathered in the past,” the Hague District Court said in a separate statement.

“All these parents are now confronted with the fact that the children in their family are part of a huge kinship network, with hundreds of half-siblings, which they did not choose,” it said.

The court considered it “sufficiently plausible” that this has or could have negative psychosocial consequences for the children.

This included psychological problems around identity and fears of incest.

“It is therefore in their interest that this kinship network is not extended any further,” the statement said.

The case is the latest in a series of fertility scandals to hit the Netherlands.

In 2020 a deceased gynaecologist was accused of fathering at least 17 children with women thinking they were receiving sperm from anonymous donors.

The year before, in 2019, it emerged that a Rotterdam doctor fathered at least 49 children while inseminating women seeking treatment.
